发布日期：2015-08

标准范围

This International Standard specifies requirements for classification of tubular cored electrodesused in the post-weld heat-treated condition for gas shielded metal arc welding of creep-resisting andlow alloy elevated temperature steels. One tubular cored electrode can be tested and classified withdifferent shielding gases.This International Standard is a combined specification providing for classification utilizing a systembased upon the chemical composition of all-weld metal or utilizing a system based upon the tensilestrength and the chemical composition of all-weld metal.1) Paragraphs and tables which carry the suffix letter “A” are applicable only to tubular coredelectrodes classified to the system based upon chemical composition with requirements for theyield strength and the average impact energy of 47 J of all-weld metal in accordance with thisInternational Standard.2) Paragraphs and tables which carry the suffix letter “B” are applicable only to tubular coredelectrodes classified to the system based upon the tensile strength and chemical composition of allweldmetal in accordance with this International Standard.3) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicableto all tubular cored electrodes classified in accordance with this International Standard.It is recognized that the operating characteristics of tubular cored electrodes can be modified by theuse of pulsed current, but for the purposes of this International Standard, pulsed current is not used fordetermining the electrode classification.
